Linux Kernel source code for the devices:
- bq aquaris U Plus
Specific sources are separated by releases with it's corresponding number. First, you should clone the project:
$ git clone https://github.com/bq/aquaris-U-Plus.git
After it, choose the release you would like to build:
Aquaris U Plus
$ mv aquaris-U-Plus kernel
$ cd kernel
$ git checkout tags/{release}
At the same level of the "kernel" directory:
Download a prebuilt gcc
$ git clone https://android.googlesource.com/platform/prebuilts/gcc/linux-x86/arm/arm-eabi-4.8
Create KERNEL_OUT dir:
$ mkdir KERNEL_OUT
Your directory tree should look like this:
- kernel
- arm-eabi-4.8
- KERNEL_OUT
Finally, build the kernel according the next table of product names:
| device | product |
|---|---|
| bq aquaris U Plus | tenshi |
$ make -C kernel O=../KERNEL_OUT ARCH=arm CROSS_COMPILE=../arm-eabi-4.8/bin/arm-eabi- {product}_defconfig
$ make O=../KERNEL_OUT/ -C kernel ARCH=arm CROSS_COMPILE=../arm-eabi-4.8/bin/arm-eabi-
You can specify "-j CORES" argument to speed-up your compilation, example:
$ make O=../KERNEL_OUT/ -C kernel ARCH=arm CROSS_COMPILE=../arm-eabi-4.8/bin/arm-eabi- -j 8
